Be it ,known that I, JOHN R.. Kun, a ctr zen ot the United States, residing at Dayton, in the eounty of Montgomery and State 5 of Ohio, have .invented certain new and neefnl Iinprovelneiits in `Can-Malring ehinery, ot which the following is a speciecation, reference being had therein to the aocdnipanying drawing. I

l lvIyirivention relates to nan-making niachinery, and, in particular, toY the sealing of cans, and inethod of sealing then'i.

It is the object of niy invention to provide a machine which will apply a sealinginedlf um, such as paraffin, to a can to seal it.

It is a further object ot iny invention to provide ineans of applying a uniform amount or' sealing` material in a restricted area. cool the sealing lnaterial, and eject the ian troni the niaehine, so that eachy can Will secure a predetermined amount of sealing inat ialand will be removed 'frein the inaehine in inished condition. i

It is iny object to provide a machine which will handle a large number of cans with :i niinilriuin amount `of nia'nual handling, so that large quantities of a uniform prodiict inay be snpplied.

nisin for bringing to rest the rotating table; and

Fig; ll is a section on the line 11-11 of Fig. 10.

' Referring to the drawings in detail:

`l is a rotating table upon which is niolinted a plinality of cylindrical supports 2.

These supports here niunted on the 'top thereof can bodies or caps 3, y

The table l carries `the suppi'ts 2 bodily, `while the supports 2 rotate upon their own axes at certain periods of their bodily revolution with the rotating table 1.

My mechanism is so arranged that I conrey on a suitable carrier the can ,bodies or capsl beinealth the apparatus for applying the sealing medium, such as paraltin, atthefsa'ine tiin'e rotating the can `bodies to evenly apply and distribute the sealing ineditnn. I then cool tlie sealing` inediuin While maintaining it in position, dueto cen'trifngalforce of the rotating support; Vihen the can er cap is `thus coi'npleted, I coinfey it te a peint Where Yit is ejected and conveyed atvey from the machine.

I'Vitli this broad eplinatieii ot' the principalA features or steps in the process, I xyill proceed to thedetails of the inventien.

rthe vrotating support consists of lthe eylinder 2, a bottoni 4, and a calpe, nfliich e1ni 'either end of the cylinder. The cap bottoin are held in their embracing poeition by ro'ds t. These rods are connected at one end to the bottoni 4, and at the other end to the cap The attachment to the cap e is effected by a supporting cap T, being mounted on the cap 5, and retained thereon by the rod G, which passee thrugh the supporting cup or cap. `The supporting cup Thas upwardly projecting rettiining walls 8 Within which the iside Wallswof the can body or` Acap 3 are located. Thepbdttoni of these Walls reste upon an ejeeting plate 9, so that ivhen thisplateis eleifated, as in Figure 6, the can er inay be ejected. 'Iliie 'ejecting plate is provided with ayrplurality if apertures 10. The ejectiiig plate itself is lnounted enan ejectingshaft 1l. It is retained thereen by a scren'7 l2.

The bottom of the shaft carries a ball i3 in jaws 14, so that the end of the shaft may ride upon the cam 15 readily, in the course of the revolution of the support and the ejector' bodily with the rotating table l.

The bottom 4 of the rotating support is provided with a sleeve 1G, through which the rod 11 passes. This sleeve turns in a bearing 17, which is formed of a downwardly projecting collar from the bottom of the rotating table l. Below this sleeve, and mounted upon 16, is a pulley 18 attached to 1G by a set-screw l5). This pulley is adapted to be engaged by the moving belt 20, through which agency the support is rotated.

Tithin the hub of the pulley, and snrrounding the ejecting shaft li. is the helical spring 2l, which engages at its lower end with the cross-pin 22. carried by the shaft ll, and at its upper cud with the sleeve 1G, thus securing a constant downward pressure on the shaft 1l, to keep the ball 13 in en- Lf-agement with the surface of the stationary table 23 or the cam l5 carried by the stationary table.

The stationary table ji is supported on legs 24. This table supports the rotating table l, the paraflin tank 25, and the mechanism for actuating the parafiin tank conti-oh the mechanism for moving the rotating table, and the mechanism .for rotating the supports 2.

Turning to the mechanism for rotating the rotatingv table l. there is provided a pulley 2b, which is fastened to the shaft 27, and a loose pulley 28. Pulley 26 is driven from any suitable source of power by a belt. On the inner end of the shaft 27 is a second gear 29, which is connected to a gear 30, mounted on a shaft 3l. This shaft has at its eXtreme endV a crank 32 and a crank-arm This erank-arni is conuected by a crossarin 34 to a reciprocatinf.Y rod S5 carried in the guides 36. which guides are mounted beneath the stationary table 23. The forward and free end of the reciprocating rod carries a head 3T and a spring 38. Pivoted upon the head isa pawl 39.which is pressed into engagement with a ratchet 40 by the spring 38, so that as 35 reciprocates it moves the ratchet one step. The ratchet 40 is connected to a shaft 4l by a pin 42. This shaft is jourualed in a dependingr collar 43, carried by the stationary table 2S. Mounted on the shaft is the rotating` table l. This rotatingr table l is strengthened by a plurality of ribs 44.r radiating from the center of the table. Thus the rotating table is moved forward step by step. Mounted on the reciprocating rod 35 is a block 45, having a cam 46 for engagement with a plunger 47. This plunger is carried in a depending bracket 48 in the bottom of the stationary table 23. It is limited in its downward movement by a cross-pin 49.

The upper end of the pin is guided in the aperture 50 in the table 23, and projects above that table until it comes in contact with the free arm 5l of a locking pawl. which is pivoted at 532 support 53, mounted on the smfacc of the table The other end of this locking pawl is designated 54, and is provided with upon a bracket or 't a hook which engages with the rotating table l on the under-side thereof, and is moved into such a position by the helical spring 56. The free end of the hook engages with a block 57. These blocks arel spaced from one another, and are so arranged that the table moves two steps bew fore it is brought to rest by the engagenient of with the block 5T. Upon the thirdstroke7 is released. and the two steps are repeated. It will be understood that this step by step mechanism may be varied to snit varying conditions.

As this rotation ot the 'able l and its supports 2 takes place. the pulleys on the supports, which are designated '15%. come in contact with the belt 20. This belt passez-1. over t-he pulleys 58, 59, and (SO. The belt engages with those pulleys which are rarrying` the cans or tops that are ha ving the para'llin applied to them, that are being dried, and those which are carrying` the cans that are being cooled. lhen thcsa` operations are completed, there is no necessity for rotating the supports.

rllhe pulley 58. which is the main driving` pulley for rotating the belt 2Oa is driven off of the shaft 27 by a gear 6l and a gear 62, which latter is mounted on a shaft G3, which is carried vertically in the table 23.

Turning to the apparatus for applying the sealing medium, such as wav or paratlin.y I provide. a water-jacketed tank which is heated by the burner (i4. l also provide supplementary burners (i5, which apply a small flame directly beneath the spouts G6, which convey the heated paratiin from the tank to the top of the rotating raps or can bodies. The purpose of having these supplementary burners is to keep the paraflin hot and fluid in the restricted area of the spout. where it might become chilled and clog the free movement of the sealing medium from the tank.

To control this application of the paratlin. I provide the :following apparatus:

The shaft 3l has mounted thereon a. cani G7, with a high point (3S thereon. A depending member 69 is pivotally supported on the bracket 70, beneath the table Q3. This swinging member Gf) is adapted to swing in the path of either the low point or the high point of this can] laterally. lt is drawn against the cam by the spring 7i. which is attached to the lower end of 69 at one end, and to the supporting table at the other end. When the swinging member jim ' the paratlin valves 78 and il) in (it) is brought in the path of the high point et Ythe cani, it is actuated bach and forth., carrying With it the link T2. the bellfcranli T3, which is pivoted beneath the table 23, and the actuating racl Tft, which carries the teeth 75. These teeth engage with a gear 76, mounted on a sha'tt i'i', which controls the spouts (je, allowing the paratlin to escape intermittentv ly, d ue to the etlcct ol. Lipfiivitiy.

It will be understood that an ejectingg pump may be substituted lor this gravity leed.

rthis intermittent 'Feeding ot' the parallin ina y be rendered inoperative by the 'folloiv .une` means:

A food treadle 8O .is provided, connected to one o't the legs 24; of the table. llhis treadle is connected to a treadle rod 8l which is niaintained in its inoperative position by the spring 82, to which it is connected. At the upper end oit the rod 82 is a bellcrank 83 connected (o a transverse rod Sil, which is suspended on brackets 85 beneath the stationary table 23. At the 'Forward end of' this transverse rod dit is a se'condbellcrank 86, connected to a link ST, which in turn is connected to the swinging ineniber 69 by a pin 89. When the pedal is depressed, thesivinging' ineiuber (i9 is brought opposite the low point on the Cain GT, and thus rendered inoperative.

When the para'l'lin is applied to the rapidly revolving` can tops on the interior as at 90, due to the fact that the can top is revolving rapidly with the support 2, I provide certain stationary guards 91, which are supports tor the cans While they are being carried to the chute.l and also act as sweeps. f

`A tter the parallin has order to rapidly cool it I provide a plurality ot air nozzles 92, ited troni a inain pipe 93, which in turn eonnnunicates with a trunk line 94. This trunk line receives its supply olf air from a 'lian 95, driven by an electric inotor 96, supported beneath the stationary table 23.

After the paraliin has been cooled, and about the time the supports, Which have nonv become stationary, approach the delivery chute, the ball 13 colnes in contact with the caln l5, thus elevating` the shait ll, which in turn carries With it the ejectine` plate 9, moving the can body into a position Where it can be picked up by the chute 0T, `which just clears the top oi the plate l). Due to the tact that the cap or can body 3 is n'ioving, it is shoved upon the delivery chute 97, between the Walls 9S, and carried away from the rnachine.

It. will he seen that it is .necessary to inove the machine a suitable number ot' steps to bringl the rotating supportsr with the can bodies directly beneaththe paratlin been applied, in

spouts, and hold thein in such a position While the can bodies are rotated and the j jarallin applied, whereupon a uieiv set ol' can bodies is brought into position.

In ordini to insure the perfect stopping` at the exact location oiI the rotatiiig table. and the holding oi. the table in that position a predetermined time, with the perfect r`elease of the table at the proper moment, l. provide a brake, which is intermittently applied. Y

The table is provided with a drunl lll), itvhieh engages with a brake band 100, cai ried on a bralte band support lOl, which positioned and adjusted, by the set-screws 102. Thus the table is always moved against the resistance of these brake bandsl` with the consequence that as soon as the power is released the table will promptly conie to rest, and not overrun its next position.

l (1f/'lied of' 0pmvittorie-#lie opei'ator places the can l'fodies to which the stalling` medium is to be applied, upon the support.` which are being n'ioved bodily on the table l, but `which are not rotating, the operator standing at the position inarlicd A; The table is moved the space or' two supports, so that two can bodies are treated sin1ultan`eously. be varied to suit the desire ot the operator, its soon as the supports conte beneath the spouts to apply the para'tlin, they are rotated by the belt 20, the paralin spo'uts are opened, the pa'ran applied., the paral'lin shut oli, and the table moved tivo steps. The rotating can bodies continue to be rotated by the belt 20, so that the centrifugal torce keeps the tluid paraffin in the proper position on the can body while it is hardening. Thile still rotating these ran rbodies are brought beneath the air spouts and chilled by the blasts oit air,` and are then linally elevated by the ejection apparatus and removed by the delivery chute.

The machine is so timed that when thc table is at rest, the parz'itlin supply is op'iiied, and just prior to its being` moved the paraliin supply is shut olif.

It Will be apparent that iny nietho'd and machine should not be `fairly liinited to a rotatingl table nor to revolving supports :For the canbodies beiiigg" sealed, but I desire to comprehend Within iny invention suitable modifications and adaptations ot it. In particular, I comprehend the use ot an endless carrier, er the inoif'ing ot the supply ol paraffin relative to the cans and their supports.
